Touch calibration for DX735

So I replaced the LCD on an all in one dx735 due to line in the screen.  Problem in the new LCD doesn't have a calibrated touch board.  I can put the old touchboard in the unit and touch will work but the calibration is off an inch or so.  Tried ordering another LCD and same issue occured, received an LCD with a touchboard that has very bad touch calibration.  Any one know how to calibrate it?
